I got the following error when trying to log in to the steempeak test site:

Oops, something went wrong. The log in request URL provided is invalid.

Pretty much anything I clicked gave that error, and a:

You need to login before continuing
Sign in with SteemConnect

Which did not work and only led back to that initial error I got.

The condensertestnet did not go anywhere at all, just a blank page with nothing.

On the steempeak proposal I could see the page, click the link, but that was about it, could not vote, or comment.

The https://testnet.steemitdev.com/ was, well to a non programmer - odd looking. Looked like error handling stuff with little down carrots for collapsing table data, a heading box, JSON, Raw Data, and Headers, box's in a menu type line.

I know not much help, but I am guessing it is not up and running right now for test postings and comments. Will check back a little later in the day, or on Monday.
